Passive Millimeter Wave (PMMW) Imaging Device for Naval Special Warfare

摘要

The long-term goal of this research is to demonstrate a prototype, lightweight, low power and low-cost passive millimeter wave (PMMW) imager that is capable of supporting Naval Special Warfare (NSW). PMMW wave imaging technology will provide NSW the capability to perform operations under severe fog/smoke conditions, and to perform concealed object and through-wall imaging. Clothing, wood, sheetrock and other construction materials are transmissive to the long wavelengths of millimeter wave radiation, allowing for the imaging of objects concealed behind them. A PMMW imaging system will provide day/night all weather vision capabilities under a variety of operations. This supports a Special Operations Command (SOCOM) Technology Development Objective for enhanced vision capabilities and supports the mission areas of combating terrorism and direct action for rescue operations. The objective of the program's initial phase is to assess the feasibility of a hand held passive millimeter wave imaging device for counterterrorism and adverse weather operational support. The objective of the second phase of the program is to fabricate and demonstrate a prototype antenna coupled microbolometer array for PMMW imaging. An antenna coupled microbolometer array will provide a lightweight, low power, and low-cost PMMW imaging sensor. The initial device will be a prototype device and will be integrated into an existing testbed (lens and data acquisition).
